Run a thread but do not want to wait to complete

Hi ,
i will be creating the thread from a different Java class and once thread is created , thread would sleep for 2 mins and start its execution but the java class from where the thread is create should not wait for thread to complete and it has to continue executing its further logic.
How to achieve this?

Oh, I also see that what you call TestThread isn't a thread, it is a Runnable so it won't have a start method and would need to be passed to a thread to run the way you want. You should read the tutorial to learn how to use them properly.
